傳回表示這個執行個體是否等於指定物件或 Int16 的值。

Equals(Int16) |
傳回值,表示這個執行個體是否等於指定的 Int16 值。 |
Equals(Object) |
傳回值,該值表示這個執行個體是否和指定的物件相等。 |
Equals(Int16)
傳回值,表示這個執行個體是否等於指定的 Int16 值。
public:
virtual bool Equals(short obj);
public bool Equals (short obj);
override this.Equals : int16 -> bool
Public Function Equals (obj As Short) As Boolean
參數
傳回
如果 true
與這個執行個體具有相同的值,則為 obj
,否則為 false
。
實作
備註
這個方法會實作為 System.IEquatable<T> 介面,而且執行方式稍微優於, Equals 因為它不需要將 obj
參數轉換成物件。
給呼叫者的注意事項
編譯器多載解析可能會考慮兩種方法多載行為中的明顯差異 Equals(Int16) 。 如果引數與定義之間的隱含轉換, obj
Int16 而且引數的類型不是,則 Object 編譯器會執行隱含轉換,並呼叫 Equals(Int16) 方法。 否則,它們會呼叫 Equals(Object) 方法, false
如果其 obj
引數不是值,它一律會傳回 Int16 。 下列範例說明兩個方法多載之間的行為差異。 在和值的案例 Byte 中 SByte ,第一個比較會傳回, true
因為編譯器會自動執行擴輾轉換並呼叫 Equals(Int16) 方法,而第二個比較會傳回, false
因為編譯器會呼叫 Equals(Object) 方法。

適用於
Equals(Object)
傳回值,該值表示這個執行個體是否和指定的物件相等。
public:
override bool Equals(System::Object ^ obj);
public override bool Equals (object obj);
public override bool Equals (object? obj);
override this.Equals : obj -> bool
Public Overrides Function Equals (obj As Object) As Boolean
參數
- obj
- Object
與這個執行個體相比較的物件。
傳回
如果 obj
是 Int16 的執行個體,並且等於這個執行個體的值,則為 true
,否則為 false
。
範例
下列程式碼範例說明如何在的 Equals
內容中使用 Int16
、比較兩個簡短的值,以及在 true
它們是否代表相同的數位時傳回 false
。
Int16 myVariable1 = 20;
Int16 myVariable2 = 20;
// Get and display the declaring type.
Console::WriteLine( "\nType of 'myVariable1' is '{0}' and value is : {1}", myVariable1.GetType(), myVariable1 );
Console::WriteLine( "Type of 'myVariable2' is '{0}' and value is : {1}", myVariable2.GetType(), myVariable2 );
// Compare 'myVariable1' instance with 'myVariable2' Object.
if ( myVariable1.Equals( myVariable2 ) )
Console::WriteLine( "\nStructures 'myVariable1' and 'myVariable2' are equal" );
else
